From haxxxen: Just a small task ( linked above) to share.. it will remove the debug message "Quit Game: No Request Event" from DEX or REBUG firmwares (the info symbol won't be removed), still searching for fake save data owner message, but not very easy to find. It seems it is hardcoded somewhere else, but not in modules.

I have found now that fake save data owner message by browsing vsh strings... I have packed both tasks into one, so you can choose both options at same time and it seperates rebug and dex firmware. it is still in old format though, sorry RedDot the info symbols will remain on both patches for manual patching:

Finally, from haz367: lv2 fixed again. Note: at least 1 of the "updated" LV2-450 patterns (copied from rogero) is causing the GLOD, need to check it more!

Anyhow... we have a winner! 450-basic patched - PS3MFW =

  • Install from any 4.xx = OK
  • Installs and boots fine...with basic patches all working

The tasks however could use a little sorting, but all this is easy enough to fix.. here's the log just in case...

Thanks again B7U3 C50SS, I've updated the v1.0.0 and v2.0.0 articles with the new mirror and +Rep!

PS: I will attach the .exe as a .rar file to this post in case the mirrors go down again as requested.

I also added PS3MFW-Builder-master v0.2.6.0 by haz367 HERE as well for those interested.

Hey! what the heck! my link went dead AGAIN! Here I've re-uploaded it on a brand new account on mega okay? I'm going to check daily for it to go down from now on. if it's down i'll re upload. until there's a more permanent fix.

ACTUALLY can you just @ PS4 News being the forum admin just hotlink the setup file as an Attachment? please it seems that the file keeps getting taken down from my service. somehow.

hmm here's a new link. Install Our MFW Builder.exe

Here's to hoping it STAYS ONLINE!
